Not really interested in the Portuguese part of the scramble as such. I'd buy a couple of packs of Askari and maybe Metropolitan troops if there were some suitable for the Great War era, though.
I'm not sure the market is there to be honest. But it's chicken and egg, isn't it? If Mark Copplestone made some folks would probably lap them up, even if they don't think they need them now. After all, there was no market for Darkest Africa at all until he made us want it with his sculpting skills.
